Abstract (en)

[origin: EP3486463A1] An output from a fuel reformation cylinder (2) is obtained based on a cylinder internal pressure and a rotational speed of the fuel reformation cylinder (2). An output adjusting operation for adjusting an output from an output cylinder (3) is executed so that a sum of the output from the fuel reformation cylinder (2) and the output from the output cylinder (3) matches with a required engine power. In this output adjusting operation, the fuel supply amount to a combustion chamber (33) or the fuel supply amount to a fuel reformation chamber (23) is controlled, during a steady operation. During a transient operation in which the required engine power is increased, the output from the output cylinder (3) is increased by increasing the fuel supply amount to the combustion chamber (33). Then, the fuel supply amount to the fuel reformation chamber (23) is gradually increased while the fuel supply amount to the combustion chamber (33) is gradually reduced, so that a heat source is shifted from the fuel to the reformed fuel.
